The incident led to a warning by Hereford and Worcester Fire and Rescue Service that anyone planning repairs at home should be aware of the dangers of working with cylinders, fuel and other flammableliquids.
The only reliable way to tell the difference is to take samples from the burn patterns and test them in a laboratory for the presence of flammable or combustible liquids.
According to the Seattle Times, the fix also involves using a system of venting tubes that in case of an incident would channel any flammable vapours or liquids directly out of the plane, and continuous monitoring of the temperature and voltage of individual cells within the battery.
